How to take email from 10 to 20% of your revenue to 40 to 50%.

If email is driving only 10 to 20% of your revenue, the path to 40 to 50% is not a secret. It is three moves, done properly, in order. This is how you improve CAC and LTV at the same time, without spending another dollar on ads.

Move 1: install every core flow

Not a welcome email and one abandoned cart reminder. The full stack:

• Welcome flow
• Site abandon flow
• Cart abandon flow
• Checkout abandon flow (yes, cart and checkout are different flows: same emails if you want, different triggers and profile filters)
• Browse abandon flow
• Post-purchase flow
• Winback flow

We wrote up exactly how long each flow should be and when it fires.

Move 2: send more campaigns

The number one problem we see inside ecommerce Klaviyo accounts: sending a couple of campaigns a week, or not sending at all.

Three to four campaigns a week is the sweet spot. It protects your unsubscribe rate while making the most revenue, and your customers get used to hearing from you on specific days and times. Consistency compounds: the brands that beat the 40% benchmark are almost always the ones whose campaigns people actually look forward to.

Move 3: focus on list growth

Here is the math that makes this the most important lever of all: if you double your email opt-in rate, you double your email revenue. Everything downstream, every flow and every campaign, multiplies off the size of your engaged list.

Start with your popup. We put together four A/B tests you can run in 15 minutes that regularly double opt-in rates, and the popup we built for Warmnest Candle drove £16,000 in its first month with a 17.4% submit rate.

What this looks like when it works

One of our jewellery clients ran exactly this playbook: full flow rebuild, new popup, and a real campaign strategy. Email went from 22% to 55% of revenue in under 90 days, while the store itself grew 59%.

Check where you stand against the 40% benchmark, then work the three moves in order.
